Pupils learn that we can see how the invisible forces of magnets work by using iron filings to help reveal the magnetic fields being produced by each magnet.
POS - notice that some forces need contact between two objects, but magnetic forces can act at a distance; describe magnets as having two poles
NaG - pupils should explore the behaviour and everyday uses of different magnets
WS - pupils should set up simple practical enquiries, comparative and fair tests; identify differences, similarities or changes related to simple scientific ideas and processes; make systematic and careful observations
